  • Patent number: 5462200
    Abstract: A hermetically sealed container is provided with an overcap and a metamorphic spike carried therein for piercing a membrane on the container. The metamorphic spike is hollow and provides a liner that defines a controlled dispensing passageway. The spike pierces the membrane and is retained within the membrane after the overcap is removed so as to provide a controlled dispensing orifice for the container. The overcap can be reapplied to the container to seal the dispensing orifice.

  • Patent number: 5395365
    Abstract: A hermetically sealed package is provided for the administration of a solution or other liquid to a patient. The package includes a blow molded container, cap, and releasable cover. The cap accommodates piercing of the cap and container with a draining spike. The cap has one or more self-closing seals or liners and can be disposed on the container so as to permit penetration of the cap and container by a piercing spike without contacting the parting line of the molded container. The cap includes a special structure for guiding the spike at the initiation of the piercing process, and the cap has an improved structure for sealingly engaging the spike upon insertion. As the container is drained, one of the container walls collapses toward the other to facilitate the draining process and provide a convenient shape for subsequent handling and storage.

  • Patent number: 5374263
    Abstract: A container having a neck with a non-tapered cylindrical upper drain portion, and a frictional interference fit collar type gripper for the withdrawal member is disclosed which results in tight interference fit. Also total effective withdrawal of the contents of the container is promoted by providing a ring like stop or seat at the bottom of the neck. The construction also will accommodate flaws and defects in the manufacture of the withdrawal member or the drain portion resulting from scratches which will otherwise permit leakage upon withdrawal of the contents. The method of the present invention is directed to manufacturing the container by which the mandrel for insertion in the neck has a lower end portion providing a seating ring, and an upper portion defining the interior portion, with an interference collar protruding inwardly in a portion spaced from the lower end portion.

  • Patent number: 5176293
    Abstract: A douche or enema dispenser is provided as a unitary hermetically sealed container and a cooperating overcap. The container has a cap structure which is removable by torsion applied through the overcap positioned over the cap structure, engageable with the adjacent container neck portion, and simultaneously rotatable as well as axially movable relative thereto. As the overcap is rotated relative to the neck portion, ribs in the overcap engage tip portions of a wing member associated with the cap structure. Since the cap structure is mounted over and sealed about a frangible web located around the container mouth that is located at the distal end of the neck portion, when sufficient torsion develops, the web is fractured, the cap is removed, and the container is opened. In opening the container, force upon walls of the liquid-filled body portion of the container is minimized.

  • Patent number: 4989649
    Abstract: A sterilizing method is provided for use with a container filling machine having components defining passages through which a fluid product flows. In one method aspect, sterilizing steam is passed through the components unitl the components have been sterilized. As the system cools and the steam condenses, the system is pressurized with gas to prevent the internal pressure in the system from decreasing below the ambient atmospheric pressure. In a further method aspect, the sterilizing process is controlled in response to sensing the temperature of one or more of the components. In yet another aspect, a common source of sterilizing steam is provided for being directed into the product filling system and simultaneously into an associated process gas supply system to sterilize both systems generally concurrently in a single pass.

  • Patent number: 4915879
    Abstract: A hermetically sealed unitary liquid container of a thermoplastic material suitable for use in inhalation therapy is disclosed as having a signal coupling. A cupshaped female connector is adapted to be threaded onto a gas inlet coupling of the container. A stem portion of the female connector defines a signal gas passageway and a flat land. A flexible elastic sleeve occludes the signal gas passageway and lies continuous with the land. When a pressure buildup is experienced within the container, gas pressure will force gas out through the signed gas passageway, and past the sleeve, while generating an audible signal, e.g., a whistling sound.
